Hello,

 

I'm trying to design a Calculator for a MMORPG Modern-War-Militia. For those of you who don't know this game It's obviosuly a war game. I'm trying to Design a Calc that when a User inputs how many of Each unit he has and then Enters the total number of units his enemy has it automatically divides out how much of each unit the Attacker(user) should send to Attack Successfully. I currently got it setup telling the Attacker if he should be able to attack successfully and telling them also if the enemy may be able to Retaliate. Let me show you an Example:

 

Attacker's units

 

40 Light Infantry

20 Light Machine Gun

20 Light Rangers

 

Defender's Units

 

10 Light Infantry

10 Light Machine Gun

10 Light Rangers

 

Totals:

Attackers Offensive Points = 160

Defenders Defensive Points = 100

 

ok, the Attacker submits in my calculator, it totals out the Attack and Defense points. But I want the calc to tell the attacker that it'd take atleast 40 Light Infantry, and 14 Light Ranger (Total Offensive Pts = 122) to Successfully Attack the Defensive Player. Anyone Have any ideas?

hi try something like this - its only basic but hopefully it will give you one direction you could take:

 

<?php

$DBConnect = mysql_connect("localhost", "root", "root");
if(!$DBConnect)
{
die("<p>ERROR1: Database unavailable</p>");
}

$DBName = "test";
if(!mysql_select_db($DBName, $DBConnect))
{
die("<p>ERROR2: Database unavailable</p>");
}


function calcOffense($offense,$number) {
$points = $offense * $number;

return $points;	
}

function calcDefence($defence,$number) {
$points = $defence * $number;

return $points;	
}

//set totals
$attacker_off_total=0;
$attacker_def_total=0;
$defender_off_total=0;
$defender_def_total=0;

$defender_array=array();
$attacker_array=array();


//loop through the attacker types of units
//this will depend on where you keep your data
//this has been pulled from a database
$sql = "SELECT * FROM tbl_Units WHERE team_id=1 ORDER BY unit_offense DESC";
$query = mysql_query($sql);

$i=0;
while($result=mysql_fetch_array($query)) {	
//calculate offensive power of each unit
$attacker_off_total += calcOffense($result['unit_offense'],$result['unit_number']);
//calculate defensive power of each unit
$attacker_def_total += calcDefence($result['unit_defence'],$result['unit_number']);

//add unit names and nubers to array for later use
$attacker_array[$i]["name"]=$result['unit_name'];
$attacker_array[$i]["number"]=$result['unit_number'];
$attacker_array[$i]["offense"]=$result['unit_offense'];
$i++;
}

//loop through the defender types of units
//this will depend on where you keep your data
//this has been pulled from a database
$sql = "SELECT * FROM tbl_Units WHERE team_id=2 ORDER BY unit_offense DESC";
$query = mysql_query($sql);

$i=0;
while($result=mysql_fetch_array($query)) {	
//calculate offensive power of each unit
$defender_off_total += calcOffense($result['unit_offense'],$result['unit_number']);
//calculate defensive power of each unit
$defender_def_total += calcDefence($result['unit_defence'],$result['unit_number']);

//add unit names and nubers to array for later use
$defender_array[$i]["name"]=$result['unit_name'];
$defender_array[$i]["number"]=$result['unit_number'];
$defender_array[$i]["offense"]=$result['unit_offense'];
$i++;
}

if($defender_def_total > $attacker_off_total) {
echo "cannot win: defender's defense too high";
}

if($attacker_off_total > $defender_def_total) {
echo "to win you need to send:<br />";

$output="";
$ttlCalcOff=0;

$calcDef = $defender_def_total;

for($i=0;$i<sizeof($attacker_array);$i++) {

	if($calcDef > 0) {

		$units = ceil($calcDef / $attacker_array[$i]["offense"]);

		//if the number of calculated units exceeds the number of units the attacker has, 
		//adjust defense points accordingly			
		if($units > $attacker_array[$i]["number"]) {
			$units = $attacker_array[$i]["number"];				

			$calcOff = $units*$attacker_array[$i]["offense"];
			$ttlCalcOff += $calcOff;

			$calcDef = $calcDef - $calcOff;
			$output .= $units." ".$attacker_array[$i]["name"]."<br />";
		} else {
			$calcOff = $units*$attacker_array[$i]["offense"];
			$ttlCalcOff += $calcOff;

			$calcDef = $calcDef - $calcOff;
			$output .= $units." ".$attacker_array[$i]["name"]."<br />";
		}
	}

}

echo $output."<br />";
echo "total offensive points for attacker: ".$ttlCalcOff."<br />";
echo "total defensive points for defender: ".$defender_def_total;


}

?>

 

have fun
